Short answer:
Content added on the first line above the default Outlook mobile signature will not be visible to the recipient when using server-side signatures.
Recommendation:
We recommend using the Outlook add-in , which displays the signature while composing and does not reroute emails.
Why is the first line not visible
When using server-side signatures, Xink looks for a specific HTML structure in the email and replaces its content with the correct signature.
In Outlook mobile apps, the first line above the default signature is included inside this HTML block.
Any content added here is therefore replaced during processing and will not appear in the final email.
User behavior
- When composing an email, typing normally places content on the second line (visible to recipients).
- To type on the first line, users must click twice, which is uncommon.
Technical explanation
The Outlook mobile app wraps the signature area in an HTML block similar to this:
<html> <br />THIS TEXT WILL NOT SHOW AT THE RECIPIENT END <br />Get Outlook for iOS </html>
Xink replaces the content inside this HTML block to ensure consistent signatures.
This design ensures that:
- Any manual changes made by users are overwritten.
- The signature is always applied—even if a user removes it in their email settings.
For example, if a user adds custom text (e.g. “John Doe”), it will be replaced when the email is sent.
